Abstract: An interference filter for the wavelength-selective filtering of light includes a stack arrangement of layer structures which has two partially permeable mirror layer structures and an intermediate layer structure arranged between the two partially permeable mirror layer structures, wherein the two partially permeable mirror layer structures form an optical resonator with a characteristic resonator wavelength k?. The material of the intermediate layer structure has, at an absorption wavelength, such an excitonic material resonance that the wavelength-dependent transmittance of the stack arrangement is determined in a wavelength range surrounding the absorption wavelength range by a strong coupling of the photons, located in the resonator, of the light with excitons of said material resonance.
